According to Hawking'a latest book there is a multiverse and more.Seth as channeled by Jane Roberts said this many years ago, that we exist in many forms and places all at one time, the same multiverse theory.  I remember from reading Seth, which I pick up and re read as leisure allows, because it is a bible of sorts, to get through life with understanding that there is more than meets the eye, so go with the flow and do your best everyday to be your best!  I will post the Seth books next for those of you that are interested.
